the stirrer are operated. The rotation of scription of the invention, such as will en.

. v My invention relates tol enameled kettles and thezlike, the object being toprovide. readily detachable means where the enamel uponthe kettle is most exposed and most often injured. The life of an enameled kettle, of course, depends, upon the enamel,

. especially in work` where acids are employed, for as soon as the enamel 1s cracked vor broken and the acid gains accessrto the metal, the kettle wall is soon destroyed. It

will also be understood that .the enamel is the shaft 12 places a strain upon that portion Vof the enamel which is connected therewith. OI" course, this strain willl be greater upon that portion 14 of the enamel than 'upon' the portions which are more distant from the shaft.

I provide mechanism for isolating the larger portion of the enamel from the shaft and so reducing the effect of the shaft upon it that there is little or no danger' of 5injuring it, and where it is not possibleI todo this, as in the case of the enamel at v14, I mount this enamel upon a removable mem- -ber 4 whichcan be readily taken out and easilybroken or cracked, and I aim to pro- .vide, a device in-which Imake detachable thatfportion ofthe kettle which is most eX- Aposed and mosteasily and most often injured. I also provide means wherein 1t 1s,

easy to, supply a new member. where the old one hasbeenremovedj. Ifurther aim to providemeans of the character describedv which can be -easily removed and another T substituted byy unskilled labor, which is generally employed with .devices of this char- Y acter. Y Y

Other objects: of my-inventionand the invention itself willprobably be better un- Y vderstood from a descriptionof an embodi- 3' ment of my invention. f

Y Figure 1 is a cross section through a ket# tleshowing an embodiment of my invention in a general way. Y

Fig. 2 is a section through ya portion` of thetop'of the embodiment shown in Fig.v

I LusVY 1, illustrating more in detail the parts which more particularly relateVV to my invention.

Fig. 3 is atop view ofthe member4. shown in Figs. 1 and 2.

At 5 is shown a kettle which is mounte in a jacket y6, both the kettle and jacket being supported upon pedestals 7 and 8.- The anotherl member substituted in 'its stead when the enamel'is injured. lI also `place the member 4 at the top of the kettle where the' contents of thel kettle are less incontact with the walls thereof than at other points, so that when the enamel 14 is broken, or

injured there will be less action upon the lmetal of the member 4 than at other portions of the kettle. I also make the walls of the'member 4 thick, sothat it will take longer forthe vacid to destroy them than lthe thinner walls of the' rest of the, kettle.

' The'top of the kettle is provided with a l neck 20 about the opening 10, and the top of this neck is provided with a flange 21, vvpreferably turned outwardly at right angles .to the neck 20. Thisflange is y y provided with a plurality of openings 22.

The member4 is provided with a flange 23 which is provided with aplurality of openings 24, corresponding to the openings 22 in the flange 21. The member 4 is connected to the kettle by bolts 25 or other suitable fastening means which pass through the openings in the lianges 21 and v23. A. gasket 26 is preferably connected between the anges, as 4illustrated in Fig. 2. An opening 27 is provided for 'the shaft through whichit passes into theinterior of the kettle. About this `shaft a packing pocket 28 isformed in the rmember 4 and' aboutthe j kettle is enameled, as shown at 9 and is provided withran opening 10, here shownf inthe to of thel kettle, the vobject of the opening'y eing to provide an ,entrance for4 means for operating upon the contents of top of this pocket a cell 29 is formed. v A mass ofv packing 30 is placed in the `pocket 28. In the form shown, this packing is compressible. being preferably Aa fibrous 4pack-- ing. A hollow ring 31- provided with an openingQ through which the shaft passes is of such size as to lit into the pocket and A,is mounted .ontop of the packing. The

ring 31 is provided with a flange '33 provided With a plurality of openings 34 through Which project means OI Connecting the member 31 to the member 4. In

vtheform shown, bolts 35 are employed.

'Whose threaded ends engage threads in holes 36 in the bottom of the cell-29.

It Will readily be understood that when .ther enamel n14'v upon the member is injuredv .inany .vvay, such as by the action of the shaft.Y and the member 4 becomes useless through the action ofthe contents lofthe kettleuponithe metal through the opening or crackinthe enamel, the member 4 may Y readily tbe .removed by simply taking out the ibolts, and a .new member substituted,

evengfbyunskilled f labor, greatly -lengthenl'ingithe-life of the kettle and cheapening the use of devices of this typeyespecially Where strong-acids are employed.

. 'I ihave .illustrated these particular lembodiments-of my invention and -the details '.shovvnwfor .the purpose of "better describing 1 Ymy invention. I do not Wish to be limited to such :form-and details, it being readily f.-un'derstoodfby those skilled inthe art-that vmany/1:departuresfmay-be madeV Jfrom both the fornifandgdetails WithoutV departingY .from;the spirit-ofthe invention.
